I had the F1 code last year and ended up paying $300 to get a new board installed. I have just had another problem with my machine, different code is oL. A very smart and ethical repair company told me to call Sears about a rework on the board. They just came out on Saturday and replaced the board for free. It took awhile to get an appointment due to them sending out the part. So if you are getting the F1 code, by all means call 1-800-659-7026 and schedule an appointment.

Unfortunately, this did not resolve my problem, will post on the oL problem blog topic next.
